10 µm process

The 10 μm process is the level of MOSFET semiconductor process technology that was commercially reached around 1971,[1][2] by leading semiconductor companies such as RCA and Intel.

In 1960, Egyptian engineer Mohamed M. Atalla and Korean engineer Dawon Kahng, while working at Bell Labs, demonstrated the first MOSFET transistors with 20 μm and then 10 μm gate lengths.[3][4] In 1969, Intel introduced the 1101 MOS SRAM chip with a 12 μm process.[5][6][7]

Products featuring 10 μm manufacturing process

• RCA's CD4000 series of integrated circuits began with a 20 μm process in 1968, before gradually downscaling and eventually reaching 10 μm in the next several years.[8]
• Intel 1103, an early dynamic random-access memory (DRAM) chip launched in 1970, used an 8 μm process.[9]
• Intel 4004 CPU launched in 1971 was manufactured using a 10 μm process.[10]
• Intel 8008 CPU launched in 1972 was manufactured using this process.[11]

The i1103 was manufactured on a 6-mask silicon-gate P-MOS process with 8 μm minimum features. The resulting product had a 2,400 μm, 2 memory cell size, a die size just under 10 mm², and sold for around $21.
